ontology iterator doesn't work

[mrmechko]

>>> ont.items()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'Trips' object has no attribute 'items'

[x for x in ont.__iter__()] does work. Apparently I return an iterator but that's not how __iter__() is supposed to work?
